Risk Determination Enabled Crypto Currency Transaction System

ABSTRACT

Systems and methods for providing risk determination in a crypto currency transaction include receiving, through a network via a broadcast by a first payer device, a first crypto currency transaction that includes a first payee public address. A first request for a determination of risk associated with the first crypto currency transaction is then identified in the first crypto currency transaction, with the first request including risk criteria. A first payee involved in the first crypto currency transaction is then identified using the first payee public address, and first payee risk information is accessed via at least one external risk information database based on the identification of the first payee. If it is determined that the first payee risk information satisfies the at least one risk criteria in the first request, the first crypto currency transaction is provided for addition to a block in a crypto currency public ledger.

BACKGROUND

The present disclosure generally relates to online and/or mobile payments, and more particularly to performing a determination of risk as part of a crypto currency transaction.

More and more consumers are purchasing items and services over electronic networks such as, for example, the Internet. Consumers routinely purchase products and services from merchants and individuals alike. The transactions may take place directly between a conventional or on-line merchant or retailer and the consumer, and payment is typically made by entering credit card or other financial information. Transactions may also take place with the aid of an on-line or mobile payment service provider such as, for example, PayPal, Inc. of San Jose, Calif. Such payment service providers can make transactions easier and safer for the parties involved. Purchasing with the assistance of a payment service provider from the convenience of virtually anywhere using a mobile device is one main reason why on-line and mobile purchases are growing very quickly.

Conventional payment service providers typically provide for payment by a payer to a payee through the use of payer accounts of the payer (e.g., credit accounts, banking account, and/or a variety of other payer accounts that may be provided by an account provider). For example, the payment service provider may provide a payment service account to the payer, and the payer may link one or more payer accounts to the payment service account (or the payment service account may include a payer account provided by the payment service provider). In a transaction between the payer and the payee, the payment service provider may then transfer funds from one of the payer accounts to a payee account of the payee (which may also be provided by the account providers or payment service provider). The use of such payer accounts, payee accounts, and payment service accounts is controlled by one or more account providers that operate to ensure that funds in the payer accounts or payee accounts are not misappropriated, and to mediate disputes associated with the transfer of funds between payer accounts and payee accounts.

An alternative to payer accounts and payee accounts provided by an account provider is the use of distributed crypto currencies such as, for example, Bitcoin, Ethereum, Litecoin, Monero, and/or a variety of other distributed crypto currencies known in the art. Distributed crypto currencies are not controlled by any central authority, but rather by a distributed network of computing devices that operate to confirm transfers of the crypto currency between payers and payees. Such decentralized distributed crypto currencies provide for the transfer of the crypto currency between users in the system, but offer no mechanism for identifying or determining risks associated with participating in a crypto currency transaction with another party. As such, a party to a crypto currency transaction is unable to ensure that they only transact with other parties that satisfy risk criteria, and instead are forced to transact “blindly” with parties that may be unknown or have unknown histories.

Thus, Applicant recognizes that there is a need for a risk determination enabled crypto currency transaction system.

DETAILED DESCRIPTION

Embodiments of the present disclosure describe systems and methods for enabling risk determinations in a crypto currency transaction. A payer creating the crypto currency transaction may choose to enable risk determinations by using a wallet application to create a crypto currency transaction that includes a request for a risk determination that designates risk criteria. As discussed below, a payer may designate the risk criteria in the crypto currency transaction in order to have a risk determination made about a payee involved in the crypto currency transaction, and/or may designate the risk criteria as required by the payee in order to have a risk determination made about the payer before the crypto currency transaction will be allowed to proceed. The payer may then broadcast the crypto currency transaction via a network, and computing device(s) that are part of a distributed network that maintain a crypto currency public ledger may receive that crypto currency transaction. In response to verifying the crypto currency transaction is valid and identifying that the crypto currency transaction includes the request to make the risk determination, the computing device(s) may add it to a risk determination memory pool. A computing device may then retrieve the transaction from the risk determination memory pool, and may identify the payee using a payee public address included in the transaction. The computing device may then access an external risk information database in order to identify risk information about the payee, and make a determination of whether that risk information satisfies the risk criteria in the request. If the risk information satisfies the risk criteria, the computing device then provides the crypto currency transaction for addition to a transaction memory pool, where computing devices that are part of the distributed network may attempt to add it to a block in the crypto currency public ledger. If the computing device determines that the risk information does not satisfy the risk criteria in the request, the crypto currency transaction is not provided for addition to the transaction memory pool such that computing devices that are part of the distributed network are prevented from adding it to a block in the crypto currency public ledger.

Referring now to FIGS. 1, 2, and 3, a method 100 for providing a risk determination in a crypto currency transaction is illustrated. In some embodiments of the method 100 described below, one or more system provider devices may operate to perform at least a portion the method 100. For example, a distributed group of one or more computing devices may operate to generate (a.k.a. “mine”) a crypto currency while creating blocks in a blockchain (also referred to below as a crypto currency public ledger), and maintain that blockchain while performing the method 100 as detailed below. In another embodiment, one or more system provider devices may perform the method 100 to provide crypto currency transaction risk determinations separate from the generation of the crypto currency to create blocks in the blockchain, and the maintenance of that blockchain. For example, a payment service provider such as, for example, PayPal, Inc. of San Jose, Calif., may utilize payment service provider device(s) to perform at least some of the method 100 (e.g., the crypto currency transaction risk determinations) discussed below, and in some embodiments may operate in cooperation with one or more other system providers (via their system provider devices), payers (via their payer devices) and/or payees (via their payee devices) to perform at least the crypto currency transaction risk determination portions of the method 100 discussed below. However, these embodiments are meant to be merely exemplary, and one of skill in the art in possession of the present disclosure will recognize that a wide variety of system providers may operate, alone or together, to provide the systems and methods discussed herein without departing from the scope of the present disclosure.

Referring now to FIG. 2, an embodiment of an electronic coin 200 is illustrated and described briefly for reference to the method 100 discussed below. The crypto currency system associated with the present disclosure defines an electronic coin as a chain of digital signatures provided by previous owners of the electronic coin to subsequent owners of the electronic coin. In the illustrated embodiment, the electronic coin 200 is owned by an owner 202, and FIG. 2 illustrates how the electronic coin 200 is defined by the digital signatures of the previous owners 204, 206, and 208. Specifically, in transaction A, a hash of the public key of owner 206 (i.e., the owner receiving, as a result of transaction A, an electronic coin 200 ₁ defined by digital signatures provided up to transaction A) and the previous transaction (not illustrated, but occurring prior to transaction A) was signed by owner 208 (i.e., the owner providing, as a result of transaction A, the electronic coin 200 ₁ defined by digital signatures provided up to transaction A) and added to an initial electronic coin (which was defined by digital signatures provided up to the transaction prior to transaction A) such that the electronic coin 200 ₁ was transferred to owner 206. Similarly, in transaction B, a hash of the public key of owner 204 (i.e., the owner receiving, as a result of transaction B, an electronic coin 2002 defined by digital signatures provided up to transaction B) and transaction A was signed by owner 206 and added to the electronic coin 200 ₁ such that the electronic coin 200 ₂ was transferred to owner 204. Similarly, in transaction C, a hash of the public key of owner 202 (i.e., the owner receiving, as a result of transaction C, the electronic coin 200 defined by digital signatures provided up to transaction C) and the transaction B was signed by owner 204 and added to the electronic coin 200 ₂ such that the electronic coin 200 was transferred to owner 202. As is understood in the art, any payee receiving an electronic coin (e.g., owner 206 in transaction A, owner 204 in transaction B, and owner 202 in transaction C) can verify the signatures to verify the chain of ownership of the electronic coin. In the discussion below, it should be understood that the term “electronic coins” is used to encompass any amount of electronic coins, from fractions of a coin (e.g., 0.00564500 electronic coins) to many multiples of coins (e.g., 56,000.00000000 electronic coins).

Referring now to FIG. 3, an embodiment of a crypto currency public ledger 300 is illustrated and described briefly for reference to the method 100 discussed below. The crypto currency public ledger 300 operates to verify that payers transferring an electronic coin (e.g., referring back to FIG. 2, owner 206 in transaction A, owner 204 in transaction B, and owner 202 in transaction C) did not “double-spend” (e.g., sign any previous transactions involving) that electronic coin. To produce the crypto currency public ledger 300, a distributed network of computing devices operate to agree on a single history of crypto currency transactions in the order in which they were received such that it may be determined that a crypto currency transaction between a payer and a payee using an electronic coin is the first crypto currency transaction associated with that electronic coin. Each device in the distributed network operates to collect new crypto currency transactions into a block, and then to increment a proof-of work system that includes determining a value that when hashed with the block provides a required number of zero bits. For example, for a block 302 that includes a plurality of transactions 302 a, 302 b, and up to 302 c, a device in the distributed network may increment a nonce in the block 302 until a value is found that gives a hash of the block 302 the required number of zero bits. The device may then “chain” the block 302 to the previous block 304 (which may have been “chained” to a previous block, not illustrated, in the same manner). When devices in the distributed network find the proof-of-work for a block, that block (e.g., block 302) is broadcast to the distributed network, and other devices in the distributed network will accept that block if all the crypto currency transactions in it are valid and not already spent (which may be determined by creating the next block using the hash of the accepted block 302). The distributed network will always consider the longest chain blocks to be the correct one, and will operate to continue to extend it. If a computing device receives two different versions of a block, it will work on the first block received, but save the second block received in case the branch of the chain that includes the second block becomes longer (at which point that device with switch to working on the branch of the chain that includes the second block).

Referring now to FIG. 4, an embodiment of a risk determination enabled crypto currency system 400 is illustrated. In the illustrated embodiment, one or more risk information provider devices 402 are coupled to one or more risk information databases 404 and to a network 406 such as, for example, the Internet. In some embodiments, at least one of the risk information provider devices 402 may be operated by a payment service provider such as, for example, PAYPAL® Inc. of San Jose, Calif., United States. In such embodiments, the risk information database(s) 404 may include risk information about payers and payees collected by the payment service provider during the course of providing payment services. However, the risk information provider device(s) 402 may be operated by a variety of risk information providers that generate, collect, and/or otherwise compile risk information (e.g., credit agencies, insurance agencies, etc.), and the risk information database(s) 404 may store a variety of types of risk data about payers and payees, while remaining within the scope of the present disclosure.

In specific embodiments, the risk information stored in the risk information database(s) 404 may include crypto-currency-blockchain-specific risk information such as, for example, whether a crypto currency public address has ever been used to receive and/or receive electronic coins, how long the crypto currency public address has held electronic coins and/or its history of holding electronic coins, whether the payment service provider has certified the crypto currency public address as legitimate, etc. Futhermore, the risk information stored in the risk information database(s) 404 may include non-crypto-currency-blockchain-specific risk information such as whether a party to the crypto currency transaction can be identified by a valid Internet Protocol (IP) address, whether a party to the transaction is associated with an approved country or location, whether a party to the transaction has performed crypto currency transactions using the system before, whether the party to the crypto currency transactions has had previous crypto currency transactions disputed or reported, etc. While some examples have been provided, one of skill in the art in possession of the present disclosure will recognize that any risk information about payers and payees may be stored in the risk information database(s) 404 while remaining within the scope of the present disclosure.

In the illustrated embodiment, one or more payer devices 408 are coupled to the network 206, and any of those payer device(s) 408 may be operated by payer(s) involved in the crypto currency transactions discussed below. Similarly, one or more payee devices 410 are coupled to the network 206, and any of those payee device(s) 410 may be operated by payee(s) involved in the crypto currency transactions discussed below. Furthermore, one or more system provider device(s) 412 are coupled to the network 206, and those system provider device(s) 412 may be part of the distributed network of computing devices that operate to maintain the crypto currency public ledger 300 discussed above. Further still, while illustrated in FIG. 4 and discussed in some embodiments below as operating separately to perform separate functions, in some embodiments, the functionality of a the risk information provider device(s) 402 and the system provider device(s) 412 may be combined such that computing devices in the distributed network of computing devices that operate to maintain the crypto currency public ledger 300 also operate to perform the risk determinations by accessing the risk information database(s) as discussed below. Thus, while a specific embodiment has been illustrated, one of skill in the art in possession of the present disclosure will appreciate that risk determination enabled crypto currency system 400 illustrated in FIG. 4 may include a variety of modification while remaining within the scope of the present disclosure.

Referring now to FIG. 5, an embodiment of memory pool subsystem 500 is illustrated. As would be understood by one of skill in the art in possession of the present disclosure, when a crypto currency transaction is broadcast through the network to a distributed network of computing devices that maintain the crypto currency public ledger, that unconfirmed crypto currency transaction is added to a memory pool on each of those computing devices, and then crypto currency transactions are retrieved by the computing devices from their memory pool, verified (i.e., the owner's signature utilizing the owner's private key is confirmed as valid for spending the crypto currency from the identified public address), and grouped in an attempt to add them as part of a block in the crypto currency public ledger (as discussed above.)

In some embodiments of the present disclosure, the memory pool subsystem 500 may be implemented in which each system provider device 502 (which are substantially similar to the system provider device(s) 412 discussed above) includes a risk memory pool 504 and a transaction memory pool 506. As discussed in further detail below, crypto currency transactions that include a request for a risk determination may be initially be added to the risk memory pool, then retrieved from the risk memory pool 504 for risk determination and, if those crypto currency transactions satisfy risk criteria, added to the transaction memory pool 506. However, if those crypto currency transactions do not satisfy risk criteria, they may be dropped such that they are not added the transaction memory pool 506. The system provider device(s) 502 may then process crypto currency transactions in the transaction memory pool 506 in substantially the same manner as discussed above. However, in other embodiments, conventional crypto currency transactions and crypto currency transactions that include requests for risk determinations may be added to a common memory pool and processed as discussed below while remaining within the scope of the present disclosure.

The method 100 begins at block 102 where a payer device creates and broadcasts a crypto currency transaction that includes a request for a risk determination. In an embodiment, at block 102 a payer and payee may be involved in a transaction where the payer is to pay the payee for products and/or services. In the embodiments discussed below, the payee accepts crypto currency, and the payer would like to pay for the transaction with crypto currency. In a specific example, a payment service provider such as, for example, PAYPAL® Inc. of San Jose, Calif., United States, provides a wallet application on the payer device that allows the payer to pay for transaction using crypto currency, and also allows the determination of a risk associated with a crypto currency transaction. For example, a payer involved in a transaction with a payee may open a wallet application on their payment device, and select an option to use a crypto currency to perform that transaction. In some embodiments, the wallet application may provide the payer the option to request that a risk determination be performed with the crypto currency transaction (i.e., in selecting an option on a wallet GUI to use a crypto currency to perform the transaction, the user may also select an option on the wallet GUI to have a risk determination be performed with the crypto currency transaction.) In other embodiments, the selection of the option to use a crypto currency to perform the transaction may include, by default, the request to perform the risk determination with the crypto currency transaction.

In some embodiments, the payer may use a payer device 408 to create the crypto currency transaction that includes the request to perform the risk determination on the payee involved in the transaction. As such, a payer who only desires to perform crypto currency transactions with payees that satisfy particular risk criteria may create their crypto currency transactions that include conventional crypto currency transaction information (e.g., a public address controlled by the payee, a transaction amount, etc.) along with a request to perform a risk determination about the payee. In some embodiments, the payer may use a payer device 408 to create, at the request of the payee, the crypto currency transaction that includes the request to perform the risk determination on the payer involved in the transaction. As such, a payee who only desires to perform crypto currency transactions with payers that satisfy particular risk criteria may require payers to create their crypto currency transactions that include conventional crypto currency transaction information (e.g., a public address controlled by the payee, a transaction amount, etc.) along with a request to perform a risk determination on the payer involved in the transaction. Furthermore, payers may use their payer device 408 to create crypto currency transactions that include requests to perform the risk determination on both the payer and the payee involved in the transaction.

In different embodiments, the request to perform the risk determination with the crypto currency transaction may identify a variety of risk criteria that should be checked for the payer and/or the payee. For example, risk criteria for performing a risk determination may include crypto-currency-blockchain-specific risk criteria such as, for example, whether a crypto currency public address has ever been used to receive and/or receive electronic coins, how long the crypto currency public address has held electronic coins and/or its history of holding electronic coins, whether the payment service provider has certified the crypto currency public address as legitimate, etc. Futhermore, the risk criteria for performing a risk determination may include non-crypto-currency-blockchain-specific risk criteria such as whether a party to the crypto currency transaction can be identified by a valid Internet Protocol (IP) address, whether a party to the transaction is associated with an approved country or location, whether a party to the transaction has performed crypto currency transactions using the system before, whether the party to the crypto currency transactions has had previous crypto currency transactions disputed or reported, etc., and/or a variety of other risk criteria that would be apparent to one of skill in the art in possession of the present disclosure. While some specific examples of risk criteria have been provided, one of skill in the art in possession of the present disclosure will recognize that any risk criteria may be identified in a crypto currency transaction while remaining within the scope of the present disclosure.

In some examples, the risk criteria may be included in the crypto currency transaction in their entirety (e.g., the crypto currency transaction may include metadata that details each risk criteria that should be checked for the payer and/or the payee (e.g., “ensure payee is located in an approved country”). However, in other embodiments, the risk criteria included in the crypto currency transaction may be provided as reference pointers that may be used by system provider devices 412 to access a risk criteria reference, which operates to reduce the size of crypto currency transactions that includes requests to perform risk determinations (e.g., a reference pointer of “1” may be identified in a risk criteria reference as “ensure party is located in an approved country”, thus allowing the identification of the risk criteria in the crypto currency transaction to be performed using a single digit). While a few examples of providing requests to perform risk determinations and/or risk criteria in a crypto currency transaction have been provided, one of skill in the art in possession of the present disclosure will recognize that the risk determination requests of the present disclosure may be provided in crypto currency transactions in a wide variety of manners while remaining within the scope of the present disclosure.

Following the creation of the crypto currency transaction, the wallet application on the payer device 408 may operate to broadcast that crypto currency transaction through the network to the system provider devices 412. As such, different payer devices 408 may create respective crypto currency transactions and broadcast those transactions through the network to the system provider devices 412. While block 102 of the method 100 describes those crypto currency transactions as including requests to perform risk determinations, one of skill in the art in possession of the present disclosure will recognize that, in some embodiments, payer devices 408 may also create conventional crypto currency transactions and broadcast them through the network to the system provider devices 412 as well.

The method 100 then proceeds to block 104 where a computing device receives crypto currency transactions. In an embodiment, at block 104, the system provider devices 412 may receive crypto currency transactions. As discussed above, the system provider devices 412 may be a part of a distributed network of computing devices that operate to maintain the crypto currency public ledger that tracks the exchange of electronic coins via the transactions broadcast through the network. As such, at block 104, any number of system provider devices 412 may receive conventional crypto currency transactions, as well as crypto currency transactions that include the request to perform the risk determinations of the present disclosure. In some embodiments, system provider devices 412 receiving crypto currency transactions at block 104 may store those crypto currency transactions in a memory pool prior to adding them to a block. However, as discussed above, in embodiments that utilize the memory pool subsystem 500 of FIG. 5, system provider devices 412 may receive crypto currency transactions that include requests for risk determinations at block 104 and store those crypto currency transactions in the risk memory pool 504, and may receive conventional crypto currency transactions at block 104 and store those conventional crypto currency transactions in the transaction memory pool 506.

The method 100 then proceeds to decision block 106 where the computing device determines whether a crypto currency transaction includes a request for a risk determination. In an embodiment, at decision block 106, a system provider device 412 may access a memory pool and retrieve a crypto currency transaction. As discussed above, in embodiments in which conventional crypto currency transactions and crypto currency transaction including requests for risk determinations are stored in a common memory pool, the system provider device 412 may access that common memory pool and retrieve either a conventional crypto currency transaction or a crypto currency transaction including a request for risk determination. Thus, at decision block 106, the system provider device 412 may operate to analyze the metadata included in the crypto currency transaction that was retrieved in order to determine whether that crypto currency transaction includes the request to perform the risk determination. For example, the request to perform the risk determination may include a risk determination bit that is set in metadata of the crypto currency transaction, while conventional crypto currency transactions will not have the risk determination bit set, and the system provider device 412 may detect whether the risk determination bit is set to determine if the crypto currency transaction includes a request to perform a risk determination.

In embodiments that utilize the memory pool subsystem 500 of FIG. 5, the system provider device 412 may access the transaction memory pool 506 and retrieve a conventional crypto currency transaction, or access the risk memory pool 504 and retrieve a crypto currency transaction that includes a request to perform a risk determination. As such, the determination at decision block 106 of whether the crypto currency transaction includes a request for a risk determination may be performed in response to performing a determination of whether to access the risk memory pool 504 (which includes crypto currency transactions with requests for risk determinations) or to access the transaction memory pool 506 (which includes conventional crypto currency transactions.)

If, at decision block 106, the computing device determines that the crypto currency transaction does not include a request for a risk determination, the method 100 proceeds to block 108 where the computing device provides the crypto currency transaction for addition to a block in a crypto currency public ledger. In an embodiment, a system provider device 412 that retrieves a conventional crypto currency transaction from a common memory pool or the transaction memory pool 506 may determine that that crypto currency transaction does not include a request for a risk determination, and at block 108 will provide the crypto currency transaction for addition to a block in the crypto currency public ledger by grouping that crypto currency transaction with other crypto currency transactions, and then incrementing a proof-of work system that includes determining a value that when hashed with those crypto currency transactions provides a required number of zero bits, thus creating the block that is added to the crypto currency public ledger.

If, at decision block 106, the computing device determines that the crypto currency transaction includes a request for a risk determination, the method 100 proceeds to block 110 where the computing device identifies a payee and/or a payer involved in the crypto currency transaction. In an embodiment, at decision block 106, a system provider device 412 may access a memory pool and retrieve a crypto currency transaction. As discussed above, in embodiments in which conventional crypto currency transactions and crypto currency transaction including requests for risk determinations are stored in a common memory pool, the system provider device 412 may access that common memory pool and retrieve a crypto currency transaction, and then analyze the metadata included in the crypto currency transaction in order to determine whether that crypto currency transaction includes the request to perform the risk determination (e.g., by detecting whether the risk determination bit is set). In embodiments that utilize the memory pool subsystem 500 of FIG. 5, the system provider device may access the risk memory pool 504 and retrieve a crypto currency transaction that includes a request to perform a risk determination. As such, the determination at decision block 106 of whether the crypto currency transaction includes a request for a risk determination may be performed in response to a determination to access the risk memory pool 504 (which includes crypto currency transactions with request for risk determinations)

If, at decision block 106, the computing device determines that the crypto currency transaction includes a request for a risk determination, the method 100 proceeds to block 110 where the computing device identifies a payer and/or a payee involved in the transaction. In an embodiment, a system provider device 412 that retrieves a crypto currency transaction having a request for risk determination from a common memory pool or from the risk memory pool 504 may determine that that crypto currency transaction includes a request for a risk determination, and at block 110 will analyze that transaction to determine whether the risk determination is requested for the payer involved in the crypto currency transaction, the payee involved in the crypto currency transaction, or both the payer and the payee involved in the crypto currency transaction.

In some embodiments, payees (e.g., merchants) may register the public addresses they use to receive crypto currency transactions with risk information providers. For example, payees may participate in the risk determination enabled crypto currency transaction system 400 by providing, through the network 406 to the risk information provider device(s) 402 via their payee devices 410, any public address that they will provide to payers to receive crypto currency from those payers in crypto currency transactions that request risk determinations. The risk information provider device(s) 402 may then store those public addresses in association with identifiers for those payees in a registered public address database that is included with or similar to the risk information database(s) 404. As such, in some embodiments, at block 110 and in response to determining that a risk determination for the payee in the crypto currency transaction has been requested, the system provider device 412 may identify the public address controlled by the payee that is included in the crypto currency transaction in order to identify the payee involved in the crypto currency transaction. As discussed in further detail below, while the identification of the public address controlled by the payee does not actually provide conclusive proof of the payees identity at this point in the method 100, the linking of the payees identity to that public address in the registered public address database/risk information database(s) 404 will allow for such identification as the method 100 continues.

Similarly, in some embodiments, payers (e.g., customers) may register the public addresses they use to send crypto currency transactions with risk information providers. For example, payers may participate in the risk determination enabled crypto currency transaction system 400 by providing, through the network 406 to the risk information provider device(s) 402 via their payer devices 408, any public address that they will use to send crypto currency to payees in crypto currency transactions that request risk determinations. The risk information provider device(s) 402 may then store those public addresses in the registered public address database/risk information database(s) 404 in association with identifiers for those payers. As such, in some embodiments, at block 110 and in response to determining that a risk determination for the payer in the crypto currency transaction has been requested, the system provider device 412 may identify the public address that is controlled by the payer and that is being used to send crypto currency in the crypto currency transaction in order to identify the payer involved in the crypto currency transaction. As discussed in further detail below, while the identification of the public address controlled by the payer does not actually provide conclusive proof of the payers identity at this point in the method 100, the linking of the payers identity to that public address in the registered public address database/risk information database(s) 404 will allow for such identification as the method 100 continues.

The method 100 then proceeds to block 112 where the computing device accesses risk information for the payer and/or the payee in external risk information database(s). In an embodiment, at block 112, the system provider device 412 may provide, to the risk information provider device(s) 402, the public address controlled by the payee that was identified in the crypto currency transaction, along with a request for risk information that corresponds to the risk criteria that was included in the request for the risk determination for the crypto currency transaction. For example, the system provider device 412 may review the request for the risk determination in the crypto currency transaction in order to identify the risk criteria that has been requested to be determined for the payee involved in the crypto currency transaction. As such, the system provider device 412 may identify the risk criteria (or reference pointers for the risk criteria, discussed above) in metadata included in the crypto currency transaction, and determine which risk information provider device(s) 402 control access to risk information (i.e., in their risk information database(s) 404) that allows for the determination of that risk criteria.) The system provider device 412 then provides the public address controlled by the payee along with that risk criteria to the determined risk information provider device(s) 402.

Similarly, in an embodiment, at block 112, the system provider device 412 may provide, to the risk information provider device(s) 402, the public address controlled by the payer that was identified in the crypto currency transaction, along with a request for risk information that corresponds to the risk criteria that was included in the request for the risk determination for the crypto currency transaction. For example, the system provider device 412 may review the request for the risk determination in the crypto currency transaction in order to identify the risk criteria that has been requested to be determined for the payer involved in the crypto currency transaction. As such, the system provider device 412 may identify the risk criteria (or reference pointers for the risk criteria, discussed above) in metadata included in the crypto currency transaction, and determine which risk information provider device(s) 402 control access to risk information (i.e., in their risk information database(s) 404) that allows for the determination of that risk criteria. The system provider device 412 then provides the public address controlled by the payer along with that risk criteria to the determined risk information provider devices 402.

At block 112, risk information provider device(s) 402 that received the identity of the payers and/or payees along with requests for risk information (via identified risk criteria) then access their risk information database(s) and use the identities of the payers and/or payees to retrieve risk information about those payers and/or payees. For example, upon receiving the identification of a public address controlled by the payee along with identified risk criteria, a risk information provider device 402 may use the identification of the public address controlled by the payee to access risk information stored in the risk information database(s) 404 about that payee (which is linked in those databases to the public address controlled by that payee as discussed above). Then, using the risk criteria identified by the system provider device, the risk information provider device 102 may retrieve any risk information stored for that payee that corresponds to those identified risk criteria, and send it through the network to the system provider device 412. As discussed above, risk criteria may be identified via reference pointers, and at block 112, the risk information provider device 402 may access a risk criteria reference using those reference pointers to identify the risk criteria used to retrieve the risk information for the payee.

Similarly, upon receiving the identification of a public address controlled by the payer along with identified risk criteria, a risk information provider device 402 may use the identification of the public address controlled by the payer to access risk information stored in the risk information database(s) 404 about that payer (which is linked in those databases to the public address controlled by that payer as discussed above). Then, using the risk criteria identified by the system provider device 412, the risk information provider device 402 may retrieve risk information for that payer that corresponds to that identified risk criteria, and send it through the network to the system provider device 412. As discussed above, risk criteria may be identified via reference pointers, and at block 112, the risk information provider device 402 may access a risk criteria reference using those reference pointers to identify the risk criteria used to retrieve the risk information for the payer.

As such, at block 112, the system provider device(s) 412 may retrieve risk information about the payer and/or the payee based on the request for the risk determination that is included in the crypto currency transactions. While the discussions above focus on system provider devices 412 that are separate from the risk information provider devices 402, in some embodiments, risk information provision and system provider functionality may be combined into single devices or entities, which allows the system provider device/risk information provider device to retrieve the risk information from the risk information database(s) itself in response to identifying the payer and/or payee and the risk criteria to be considered for the crypto currency transaction. As such, one of skill in the art in possession of the present disclosure will recognize that the accessing of the risk information may be performed in a variety of manners other than those that have been explicitly described while remaining within the scope of the present disclosure.

The method 100 then proceeds to decision block 114 where the computing device determines whether the risk information satisfies risk criteria in the request for the risk determination. In an embodiment, at decision block 114, the system provider device 412 determines whether the risk information received for the payer and/or the payee at block 112 satisfies the risk criteria identified in the request for the risk determination for the crypto currency transaction. Thus, at decision block 114, the system provider device 412 may compare the risk information received for the payee to the risk criteria included in the request for the risk determination about the payee involved in the crypto currency transaction. Similarly, at decision block 114, the system provider device 412 may compare the risk information received for the payer to the risk criteria included in the request for the risk determination about the payer involved in the crypto currency transaction

In specific examples, and in addition to the risk information/risk criteria discussed above, the determination of whether the risk information satisfies the risk criteria included in the risk determination about the payee in the crypto currency transaction may include whether payee has transacted on the crypto currency public ledger before and, if not, how long has the payee public address held electronic coins on the crypto currency public ledger; whether the payee has transacted previously with the payer, a number of disputed transaction associated with the payee, etc. Any of these determinations may result in an assignment or adjustment of a risk score that may be compared to a risk threshold that determines whether the risk information satisfies the risk criteria included in the risk determination about the payee in the crypto currency transaction. While a few specific examples have been provided, one of skill in the art in possession of the present disclosure will appreciate that any type of risk information about a payee may be retrieved compared to any type of risk criteria to determine whether it satisfies that risk criteria while remaining within the scope of the present disclosure.

In a specific examples, and in addition to the risk information/risk criteria discussed above, the determination of whether the risk information satisfies the risk criteria included in the risk determination about the payer in the crypto currency transaction may include whether the payer is a verified person or an approved entity based on prior transactions received at the payer public address, whether the payer public address has been certified by the payment service provider, etc. Any of these determinations may result in an assignment or adjustment of a risk score that may be compared to a risk threshold that determines whether the risk information satisfies the risk criteria included in the risk determination about the payer in the crypto currency transaction. Furthermore, as discussed herein, the risk threshold may determine how many confirmations a block including the crypto currency transaction will be required before it is accepted by the payee. While a few specific examples have been provided, one of skill in the art in possession of the present disclosure will appreciate that any type of risk information about a payer may be retrieved compared to any type of risk criteria to determine whether it satisfies that risk criteria while remaining within the scope of the present disclosure.

If, at decision block 114, the computing device determines that the risk information satisfies the risk criteria in the request for the risk determination, the method 100 proceeds to block 108 where the computing device provides the crypto currency transaction for addition to a block in a crypto currency public ledger substantially as described above. As discussed below, the provisioning of the crypto currency transaction for addition to a block in the crypto currency public ledger may be performed in a variety of manners that will fall within the scope of the present disclosure.

For example, in situations where the memory pool subsystem 500 of FIG. 5 is used in the risk determination enabled crypto currency transaction system 400, the determination that the risk information satisfies the risk criteria in the request for the risk determination may result in the system provider device then moving that crypto currency transaction to the transaction memory pool 506. Once stored in the transaction memory pool 506, any of the system provider devices 412 may group the crypto currency transaction (for which the risk determination process has determined that risk criteria has been satisfied) with other crypto currency transactions, and then increment a proof-of work system (e.g., determining a value that when hashed with those crypto currency transactions provides a required number of zero bits,) to create the block that is then added to the crypto currency public ledger. As such, when the memory pool subsystem 500 is implemented as part of the risk determination enabled crypto currency transaction system 400, crypto currency transactions that include requests for risk determinations may undergo a multi-memory pool process in which risk determinations for those crypto currency transaction are conducted from crypto currency transactions in a risk memory pool and, if the payer and/or payee in those crypto currency transactions satisfy risk criteria, those crypto currency transaction are then moved to a transaction memory pool where they may then be added to a block in the crypto currency public ledger.

In such embodiments, a risk determination fee system may be implemented where system provider devices 412 are incentivized to perform risk determinations. For example, crypto currency transactions including requests to perform risk determinations may be broadcast by payer devices and added to the risk memory pool 506, where first system provider devices may perform risk determinations for payers and/or payees in those crypto currency transactions and receive a fee for doing so. If the payers and/or payees in those crypto currency transactions satisfy the risk criteria, those crypto currency transactions may be rebroadcast to second system provider devices who will add those crypto currency transactions to the transaction memory pool, and group those crypto currency transactions in an attempt to add them to a block in the crypto currency public ledger, and also receive a fee for doing so. Similarly, a determination that the payers and/or payees in those crypto currency transactions do not satisfy the risk criteria, those crypto currency transactions will not be rebroadcast to second system provider devices such that they are not added the transaction memory pool and will not be included in any blocks on the crypto currency public ledger. One of skill in the art in possession of the present disclosure will recognize that, in such a system, the first system provider devices and the second system provider devices discussed above may perform both risk determination and block creation in order to collect fees for each.

In another example, in situations where the risk determination enabled crypto currency transaction system 400 groups conventional crypto currency transaction and crypto currency transactions with requests for risk determinations in a common memory pool, the determination that the risk information satisfies the risk criteria in the request for the risk determination may result in the system provider device then grouping the crypto currency transaction (for which the risk determination process has determined that risk criteria has been satisfied) with other crypto currency transactions, and then incrementing a proof-of work system (e.g., determining a value that when hashed with those crypto currency transactions provides a required number of zero bits,) to create the block that is then added to the crypto currency public ledger. As such, system provider devices may perform risk determinations for crypto currency transaction (for a fee in some embodiments) and, if the payer and/or payee in those crypto currency transactions satisfy risk criteria, then attempt to create a block for addition to the crypto currency public ledger.

In some embodiments, the addition of the crypto currency transaction to a block in the public ledger at block 108 following a determination at decision block 114 that its risk information satisfies the risk criteria in its request may provide for a higher trust level associated with the crypto currency transaction. For example, upon having the determination that made that the risk information satisfies the risk criteria in the request in the crypto currency transaction, the crypto currency transaction may be marked as a “trusted” or “risk certified” transaction. As would be understood by one of skill in the art in possession of the present disclosure, upon being initially added to a block in the crypto currency public ledger by a first computing device in the distributed network, other second computing devices in the distributed network may confirm that block, and payees typically require a minimum number of a confirmation of a block (e.g., 6 to 10, and in some cases more depending on the transaction) before its transactions are accepted as permanent. However, payees may required fewer confirmations to accept as permanent a crypto currency transaction in a block if that crypto currency transaction is “trusted” or “risk certified” as discussed above. Furthermore, payees may required more confirmations to accept as permanent a crypto currency transaction in a block if that crypto currency transaction is not “trusted” or “risk certified” as discussed above.

If, at decision block 114, the computing device determines that the risk information does not satisfy the risk criteria in the request for the risk determination, the method 100 proceeds to block 116 where the computing device prevents the crypto currency transaction from being added to a block in the crypto currency public ledger. In an embodiment, at block 116. As discussed below, the prevention of the crypto currency transaction from being added to a block in the crypto currency public ledger may be performed in a variety of manners that will fall within the scope of the present disclosure.

For example, in situations where the memory pool subsystem 500 of FIG. 5 is used in the risk determination enabled crypto currency transaction system 400, the determination that the risk information does not satisfy the risk criteria in the request for the risk determination may result in the system provider device then rejecting that crypto currency transaction such that it is not added the transaction memory pool 506. By preventing the crypto currency transaction from being added to the transaction memory pool 506, system provider devices 412 will not be able to group the crypto currency transaction (for which the risk determination process has determined that risk criteria has not been satisfied) with other crypto currency transactions as part of any block that will be added to the crypto currency public ledger. As such, when the memory pool subsystem 500 is implemented as part of the risk determination enabled crypto currency transaction system 400, crypto currency transactions that include requests for risk determinations that are not satisfied will undergo a first portion of a multi-memory pool process in which risk determinations for those crypto currency transaction are conducted from crypto currency transactions in a risk memory pool and, if the payer and/or payee in those crypto currency transactions does not satisfy risk criteria, those crypto currency transaction are prevented from entering a transaction memory pool such that they may not be added to a block in the crypto currency public ledger.

In another example, in situations where the risk determination enabled crypto currency transaction system 400 groups conventional crypto currency transaction and crypto currency transactions with requests for risk determinations in a common memory pool, the determination that the risk information does not satisfy the risk criteria in the request for the risk determination may result in the system provider device then dropping the crypto currency transaction (for which the risk determination process has determined that risk criteria has been satisfied) such that it is not part of any block that the system provider device then attempt to add to the crypto currency public ledger. As such, system provider devices may perform risk determinations for crypto currency transaction and, if the payer and/or payee in those crypto currency transactions do not satisfy risk criteria, that crypto currency transaction is not grouped with any other crypto currency transaction for attempted addition to block in the crypto currency transaction, and is thus prevented from being added to a block for addition to the crypto currency public ledger.

Thus, systems and methods for enabling risk determinations in a crypto currency transaction have been described that allow payers and/or payees participating in crypto currency transactions to request a determination of the risk involved with either or both parties in the crypto currency transaction and, if risk criteria is not satisfied by either or both of those parties, prevent that transaction from completing. A payer creating the crypto currency transaction may create a crypto currency transaction that includes a request for a risk determination that designates risk criteria for a payer and/or the payee involved in that crypto currency transaction. The payer may then broadcast the crypto currency transaction via a network, and computing device(s) may receive that crypto currency transaction, identify the request to make the risk determination, and add it to a risk determination memory pool. A computing device may then retrieve the transaction from the risk determination memory pool, identify the payee and/or payer involved in the crypto currency transaction, and access an external risk information database in order to identify risk information about the payer and/or payee. A determination is then made of whether the risk information satisfies the risk criteria in the request, and if the risk information satisfies the risk criteria the crypto currency transaction is provided to a transaction memory pool so that it may be added to a block in a crypto currency public ledger, while if the risk information does not satisfy the risk criteria in the request the crypto currency transaction is not provided to the transaction memory pool such that it is prevented from being added to a block in a crypto currency public ledger.

The method of claim 7, wherein the receiving the first crypto currency transaction that includes the first payee public address further includes: receiving, by the computing device, the first crypto currency transaction and storing the first crypto currency transaction in a risk determination memory pool; and retrieving, by the computing device, the first crypto currency transaction from the risk determination memory pool in order to identify the first request for the determination of risk associated with the first crypto currency transaction.
 11. The method of claim 10, wherein the first crypto currency transaction is provided for addition to the block in the crypto currency public ledger by providing the first crypto currency transaction in a transaction memory pool subsequent to determining that the first payer risk information satisfies the at least one risk criteria in the first request.
 12. The method of claim 7, wherein the identifying the first payee involved in the first crypto currency transaction further includes: accessing, by the computing device, at least one registered public address database; and identifying, by the computing device, the first payee that was previously associated with the first payee public address in the at least one registered public address database.
 13. The method of claim 7, wherein the providing the first crypto currency transaction for addition to the block in the crypto currency public ledger includes: adding, by the computing device, the first crypto currency transaction to the block; and performing, by the computing device, calculations on the block that are configured to add the block to the crypto currency public ledger.
 14. A non-transitory machine-readable medium having stored thereon machine-readable instructions executable to cause a machine to perform operations comprising: receiving, through a network via a broadcast by a first payer device, a first crypto currency transaction that includes a first payee public address; identifying, in the first crypto currency transaction, a first request for a determination of risk associated with the first crypto currency transaction, wherein the first request includes at least one risk criteria; identifying, using the first payee public address, a first payee involved in the first crypto currency transaction; accessing, via at least one external risk information database and based on the identification of the first payee, first payee risk information; determining that the first payee risk information satisfies the at least one risk criteria in the first request; and providing, in response to determining that the first payee risk information satisfies the at least one risk criteria in the first request, the first crypto currency transaction for addition to a block in a crypto currency public ledger.
 15. The non-transitory machine-readable medium of claim 14, wherein the operations further comprise: receiving, through the network via a broadcast by a second payer device, a second crypto currency transaction that includes a second payee public address; identifying, in the second crypto currency transaction, a second request for a determination of risk associated with the second crypto currency transaction, wherein the second request includes at least one risk criteria; identifying, using the second payee public address, a second payee involved in the second crypto currency transaction; accessing, via the at least one external risk information database and based on the identification of the second payee, second payee risk information; determining that the second payee risk information does not satisfy the at least one risk criteria in the second request; and preventing, in response to determining that the second payee risk information satisfies the at least one risk criteria in the second request, the second crypto currency transaction from being added to a block in the crypto currency public ledger.
 16. The non-transitory machine-readable medium of claim 15, wherein the operations further comprise: identifying, using the first payer public address, a first payer involved in the first crypto currency transaction; accessing, via the at least one external risk information database and based on the identification of the first payer, first payer risk information; determining that the first payer risk information satisfies the at least one risk criteria in the first request; and providing, in response to determining that each of the first payee risk information and the first payer risk information satisfy the at least one risk criteria in the first request, the first crypto currency transaction for addition to the block in the crypto currency public ledger.
 17. The non-transitory machine-readable medium of claim 14, wherein the receiving the first crypto currency transaction that includes the first payee public address further includes: receiving the first crypto currency transaction and storing the first crypto currency transaction in a risk determination memory pool; and retrieving the first crypto currency transaction from the risk determination memory pool in order to identify the first request for the determination of risk associated with the first crypto currency transaction.
 18. The non-transitory machine-readable medium of claim 17, wherein the first crypto currency transaction is provided for addition to the block in the crypto currency public ledger by providing the first crypto currency transaction in a transaction memory pool subsequent to determining that the first payer risk information satisfies the at least one risk criteria in the first request.
 19. The non-transitory machine-readable medium of claim 14, wherein the identifying the first payee involved in the first crypto currency transaction further includes: accessing at least one registered public address database; and identifying the first payee that was previously associated with the first payee public address in the at least one registered public address database.
 20. The non-transitory machine-readable medium of claim 19, wherein the providing the first crypto currency transaction for addition to the block in the crypto currency public ledger includes: adding the first crypto currency transaction to the block; and performing calculations on the block that are configured to add the block to the crypto currency public ledger.
